Hi…
How to create comments like template system to an Entity? I want to implement comments for every entity instance… Can anybody suggest me?
Hi,
I created an example of exactly that in here: GitHub - balvi/cuba-example-declarative-comments: CUBA example that shows how to use the declarative-controllers application component
Perhaps ill make it a app component if there is demand for it 
Bye
